There are also MST based cases with the same idea - a spice case side and a couple of MST ports. The disadvantage to the combined splice case and drop case is that you have to put one at every location you want to have drops, or run a lot of long parallel drop cables from pole to pole. The combined cases are also normally installed in-line without slack storage. If you do that it means all of your splicing and repair work needs to be done in the air from a bucket truck. Depending on where you are located that might be an acceptable option - or it might completely suck. Personally in NW Ohio it completely sucks from November to March trying to work fiber in a bucket. By keeping the splice case and the MST (or the drop case) separate you can minimize the number of splice cases by putting 3, 4 or more multiport cables into one splice case. At the middle pole put a splice case and a 50’ stub MST (with 2-12 drop ports) on a 100’ slack loop. At the poles on either side (or all sides if this is a X intersection) put MST’s with 250/350/450/750’ tails into the splice case and then place the MST’s on the outer poles. This way you have one splice case that you put on a snowshoe and hang it back on the line with MST’s on the central pole and all the surrounding poles. You can do all the splicing and repair work on the ground in a nice warm trailer. This same method could be used with a case made just for drops or by not using the splicing side of a ATC type of case if you really prefer that method. 4 port MST’s with 250’ tails can be had in bulk for ~$100, 8 port for ~$150. Drop cables with one Opti-tap end vary from ~$45 to $100 depending on length. The advantage to a OptiTap style cable is you can send pretty much any trained monkey out to plug one in. No special knowledge is needed other than "don’t touch the end of the connector” and it can be done in pretty much any weather in less than a minute.
